public interface Schema extends Map<Name,AttributeType>
A schema is organized as a map of Name
to AttributeType
. In each name,type
tuple, the name matches the name of the type.
//create some attribute types AttributeType pointType = new AttributeTypeImpl( new NameImpl( "http://www.opengis.net/gml", "PointType" ), ... ); AttributeType lineStringType = new AttributeTypeImpl( new NameImpl( "http://www.opengis.net/gml", "LineStringType" ), ... ); AttributeType polygonType = new AttributeTypeImpl( new NameImpl( "http://www.opengis.net/gml", "PolygonType" ), ... ); //create a schema Schema schema = new SchemaImpl( "http://www.opengis.net/gml" ); //add types to the schema schema.add( pointType ); schema.add( lineStringType ); schema.add( polygonType );
The intention of a schema is to provide a resuable set of attribute types. These types are used when building attribute instances.

.
type
- The type to add.Schema profile(Set<Name> profile)
A profile of a schema is a subset of the schema, and it also a schema itself.
Used to select a subset of types for a specific application. Profiles often are used to express limitiations of a source of data.
profile
- The set of names which corresond to entries that will make up the profile.Copyright © 1996–2019 Geotools. All rights reserved.
